Hi,
I have recently purchased a Pioneer PDP434HDE Plasma to go with my older but reliable Sony 725DVD Player, Sony STR930 Amp, Freeview Digibox and Panny VCR.
I am looking to add a video scaler to this kit but need to know which is best for the kit I have and how to connect it all.
Also are the Philips Prontos a good addition to an AV setup.
Thanks in advance for your time / advice
